The proposed research will provide valuable information about the physiological functioning of trees in northern Australia. Experiments will elucidate mechanisms that can result in variation in water-use efficiency among different tree species. Such a mechanistic understanding will have multiple benefits: (1) results will be able to be incorporated into process-based models of carbon and water cycling in the north-Australian landscape; (2) they will provide valuable information for land managers interested in optimizing both plant biomass production and water resource management; and (3) they will provide a critical test of proxy methods for identifying high water-use efficiency in taxonomically diverse tree species.

拟议中的研究将提供有关澳大利亚北方树木生理功能的有价值的信息。 实验将阐明可能导致不同树种之间水分利用效率差异的机制。 这样一个机械的理解将有多方面的好处：（1）结果将能够被纳入基于过程的模型的碳和水循环在澳大利亚北部的景观;（2）他们将提供有价值的信息，土地管理人员有兴趣在优化植物生物量生产和水资源管理;和（3）他们将提供一个关键的测试代理方法，以确定高水分利用效率的分类不同的树种。
